Hi, I am about to start chemotherapy and herseptin treatment on the 3rd of January, I have her 2 positive breast cancer with a 2ins tumour leading off the multiple others,stage,2/3, I am so scared about all this and what the side effects are going to be. I have spoken to my consultant and it sounds very bleak. I'm having 6 sessions and maybe surgery. My question is has anyone else been through the same as this and do you have any advice please to help.
